Risk indicators for Pasteurella haemolytica related summer pneumonia in lambs in The Netherlands were investigated using a mail questionnaire survey of 860 flocks. The response rate was 64% (n = 550). Multivariate risk analysis indicated that taking sheep to sheep fairs, the purchase of sheep and/or lambs, the lack of possibility for indoor housing, and an increased flock size were associated with increased risk of occurrence of summer pneumonia in lambs of the home flock.
通过对860个羊群进行邮件问卷调查,对荷兰羔羊中与溶血巴斯德氏菌相关的夏季肺炎的风险指标进行了调查。回复率为64%(n = 550)。多变量风险分析表明,带羊去参加羊展、购买绵羊和/或羔羊、没有室内饲养的可能性以及羊群规模增加与家庭羊群中羔羊发生夏季肺炎的风险增加有关。
